方式三：
custom.cs:
public class custom { private int _id; private string _cname; private string _ename; private int _departID; private int _age; private string _password; private string _departname; public string departname { get { return _departname; } } public int id { get { return _id; } } public string cname { get { return _cname; } } public string ename { get { return _ename; } } public int departID { get { return _departID; } } public int age { get { return _age; } } public string password { get { return _password; } } public custom(int ID,string DepartName,string CName,string EName,int DepartID,int Age,string PassWord ) { _id = ID; _departname = DepartName; _cname = CName; _ename = EName; _departID = DepartID; _age = Age; _password = PassWord; } } department.cs:
public class department { private int _id; private string _departname; private string _description; public int id { set { _id = value; } } public string departname { set { _departname = value; } } public string description { set { _description = value; } } public department(int ID,string DepartName,string Description) { _id = ID; _departname = DepartName; _description = Description; } } 还有一种方式就是结合方式一和方式三来设计
